HYDRANT.

SPECIFICATION forming part of- Letters Patent No. 300,925, dated June 24, 1884.

Application filed December 17, 1883. (No model.)

To all whom it may concern Be it known that I, JOHN WARD, of the village of Lansingburg, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Hydrants, of which the following is a specification.

My invention relates to hydrants, and, in some of its features, to improvements upon the hydrant shown and described in Letters Patent No. 224,061, granted to me as inventor and assignor February 3, 1880. The hydrant illustrated and described in said patent was constructed with a wastevent which was opened and closed by the combined action of the stem-rod, its threaded connection with a nut that was recessed within the back of the gate, and the wedging engagement of the back of said nut with the hydrant interior, said stem-rod being actuated, when turning on its threaded connection with the nut in the gate, to enter and close the vent-opening when the gate was open, and to disclose it when the gate was closed.

To improve the operation of the means constructed to wedge the hydrant-gate to its seat, to prevent the gate from sliding over its seat, to close or open, and to make the means which closes and discloses the waste-vent automatically adjustable, are the main objects of my invention.

One feature of my invention consists, as will be fully detailed hereinafter, in the construc-' tion upon the end of the hydrant-stem rod of an adjustable plug that is pivoted thereto, so that the stem-rod turns in the plug as it forces the latter into or draws it from the vent-opening, and the plug enters and comes from out of the latter without turning within it.

Another feature of my invention consists, the details of which will be fully given hereinafter, in the combination, with a hydrant-gate, of an angular-form recesshaving a wedge-form incline or bevel constructed on its inner face, an angular wedge form nut adapted to fit loosely in said recess and threaded to the stemrod of the hydrant; openings in the said gate above and below said angular-form recess for the free passage of the stem-rod to and through, its threaded connection made with the wedgeinterior to arrest the descent of the gate when opposite the entry-port, and a vertical guideway within the hydrant interior, along and over which the outer face of the wedge-nut moves when actuated by the stem-rod and its threaded connection made therewith.

My invention also consists in the combina tion, with a hydrant-gate, and made on the outer face thereof, of sinks constructed with downwardly and inwardly beveled surfaces, as will be more fully detailed hereinafter.

My invention also consists, as will be detailed in the claims, of such subcombinations of the parts as perform specific functions.

In the accompanying two plates of drawings, forming apart of this specification, there are shown eleven figures, illustrating my invention and improvements, with the same designation of parts by letter-reference used in all of them, and of which?- Figure 1' shows a perspective of a hydrant with a part of the casing cut away to show the interior, said hydrant thus illustrated containing my invention and improvements. Fig. 2 illustrates a longitudinal vertical section of the hydrant shown in Fig. 1, and as taken at right angles to the vertical plane of the gate face. Fig. 3 illustrates in perspective the lower part of the hydrant, taken with thatside of it which is opposite the 'entry'port turned toward the sight, and a part of the exterior casing removed, so as to show the face of the gate-seat, the gate and stem being omitted to illustrate the position of the stops by which the descent of the gate is arrested. Fig. 4 illustrates, as relatively enlarged when compared with the other parts, a perspective of the lower end of the stem-rod and the adjustable plugattached thereto, with the adjacent parts in the hydrant-base producing the vent opening and closing seat for the plug shown.

in section, and the vent illustrated as open. Fig. 5 shows the same parts as are shown in Fig. 4, with the vent closed by the plug on the end of the stein-rod. Fig. 6 is a perspective end of the stem-rod and plug on the line 00 x of Fig. 4. Fig. 9 isaperspective of the hydrantgate with its back turned toward the sight,

and with the nut removed from the recess to show the form of the latter. Fig. 10 is a perspective of the wedge-form nut and with what is its outer face when the nut is inserted in the recess shown as turned toward the sight in the illustration. Fig. 11 is a perspective of the nut with what is its interior face when inserted turned toward the sight in the figure, all the illustrations shown at Figs. 9, 10, and 11 being drawn in an enlarged proportion as compared with the size of the same parts where shown in the other figures.

The several parts of the hydrant are desig nated by letter-reference and their function explained as follows:

The letter H indicates the cylindrical form exterior of the hydrant; 0 its dischargeopening, and E its entry-port.

The letter S designates the stem-rod, which is shown as threaded at T; and G indicates the gate, made with the closing face 9, and on its inner side, the angular form cross-re-t cess R, constructed with the incline or wedg- V tween said nut and the gate by means of the ing face W.

The letters A A indicate vertical passages or openings made through the back of the gate above and below the said angular recess, j

said openings being for the vertical passage of the stem-rod.

structed with the wedging-surface W the flat top surface, a", and the vertical side surface, n

This wedge-nut is adapted to fit loosely in the recess R, and with the inclined surface W of the latter constructed to be parallel with the wedging-face 7 of the nut when the latter has been placed within the recess and threaded;

onto the stem-rod.

as to subtend the edges of the gate back' on its inner face; and J designates another guideway placed also on the hydrant interior over the entry-port E, along the surface of which guide J the outer closing face of the gate passes, so

that when the gate is moved vertically it travels betweenthe guides I I and the guide J, there being room enough between these guides for the free passage of the gate and its-lateral movement toward its seat (I, when actuated to;

close.

The letter B designates a guideway for the nut-wedge N along and over the vertical face; of which the vertical side a of said nut loosely passes when the gate is being moved up and down, and with which guidewayB said nut; engages on its vertical face a when the de-. scent of the gate is arrested by the stops, and

it is being moved laterally toward its closing seat by the combined action of the stem-rod, the wedgin g incline W on the back of the gate, and the wedging-nut N. The guideway B is preferably made to taper slightly downwardly and inwardly, although it will operate in conjunction with the wedge-nut N when made straight.

Theletters b b indicate stops on the stem rod.

The letters m m indicate recesses formed in the outer disk-face of the gate, and these recesses are beveled inwardly and downwardly to intermediate partitions horizontally arranged. The object and purpose of these recesses and partitions is to utilize the pressure of the water-main to promptly force the gate downwardly and inwardly from off its closing seat, so soon as the wedging engagement at the back of the gate has been released, and before it commences to rise when being opened, to thus prevent the grinding and cutting away of the packing, which occurs when the gate slides over the latter. The plug I is made adjustable by means of. a pin, that is projected upwardlytherefrom, and which pin is prorecess R, the stem-rod forces the plug P into the vent V to close the latter. When the stemrod is turned to close the gate,the latter descends until itreaches the stops D D, and as the-turning of the stem-rod is continued the The letter N designates awedge-form nut conwedging-surface W of the wedge-nut engages with the incline W in the recess R at the back of the gate, to force the latter toward its seat d, thus closingthe entry-port, and as the turning of the stem-rod is proceeded with the plug P is raised from out of the vent V to allow the escapeof the water remaining in the hydrant.

To enablethe hydrant to be operated with a stem-rod of ordinary size and diameter, and The letters I I indicate vertical guides arranged oppositely on the hydrant interior, so

so that the rod shall be relieved from the lateral pressure against itfroin the water-main acting on the gate-face, the guide B is used, and with which the vertical face a of the wedge-nut engages while forcing. the gate to its seat; but by using a heavy stem-rod, which is strong enough to resist the lateral pressure against it, the guide B may be omitted.

In my patent before alluded to the hydrant is shown and described as forced to its closing seat by the engagement of an inclined surface produced on the outer face of a nut that is located in a rectangular recess in theback of the gate, and an inclined surface on the wall of the hydrant interior, but without coincidentlyarranged inclined surfaces produced where the nut and the back of the gate are in contact. As a sequence,when the gate of this older device commenced toclose, it was from necessity compelled to slide over and along the packing upon its closing seat. In the device shown herein the wedging of the gate to its seat is wholly accomplished after the descent of the gate has been arrested, and as a sequence the latter is forced laterally to its seat, and it does not slide across the face of the seat to cut and wear away its packing.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. In a hydrant, the combination of a stemrod constructed to descend to open the entryport gate, and to rise in closing it, a .ventopening arranged in the hydrant bottom or base, connecting directly with the interior of said hydrant, and a pivoted plug on the end of said stem-rod, with said parts constructed and arranged to operate substantially in the manner as and for the purposes set forth.

2. In a hydrant, the combination of the stem-rod S, the gate G, made with the transverse wedge-form recess R, and the vertically coincident stem-rod passages a above and below said recess, the threaded wedge-form nut N, adapted to loosely enter said recess and be therein threaded to the stem rod, and the stops D, with the said parts constructed and arranged to operate substantially in the manner as and for the purposes set forth.

3. In ahydrant, the combination of the stemrod S, the gate G, made with the wedge-form recess R in its back and the openings a at the top and bottom of said recess, the wedge-form nut N, constructed to loosely enter said recess and be'therein threaded to the stem-rod, and the guide J, with said parts constructed and arranged to operate in the manner as and for the purposes set forth.

4. In a hydrant, the combination of the stemrod S, the gate G, constructed with the wedge form recess R on its inner face and the stemrod passages a above and below said recess, the wedge-form nut N, adapted to loosely enter said recess and be therein threaded to the stem-rod, the guides I I, and the stops D D, with said parts arranged to operate substantially in the manner as and for the purposes set forth.

5. In combination with a hydrant, the entry-port gate G, made with the recesses m on its outer face inside of its closing rim-seat, as 50 and for the purposes set forth.
